A.F. Samoilov: from synapse to systemic organization of functions

One of the world’s leading physiologists of the late 19th — the first third of the 20th centuries, Doctor of Medicine, Professor, Head of the Department of Physiology of Kazan University, Lenin Prize winner, Honored Scientist of the RSFSR Alexander Filippovich Samoilov (1867, Odessa — 1930, Kazan) is known as one of the creators of the theory and practice of electrocardiography, introduction of this method into the clinic. In 1924, A. F. Samoilov proved the chemical nature of the transition of excitation from a nerve to a muscle. Many fundamental works of the scientist are devoted to spinal and central nervous mechanisms. As a student and follower of I. M. Sechenov, A. F. Samoilov proceeded to formulate the principles of systematic organization of functions in animals and humans based on the material of his works. The scientists studied the systems of coding characters in the notation of notes. On the example of the circular rhythm of muscle excitation described by him in 1929, A. F. Samoilov anticipated the model of an automatic self-regulating system and systemic social circular interaction.
